British Jewish Community Shifting Towards Green Party and Reform UK as Backing for Main Parties Drops

Findings show a new electoral split among the UK Jewish community, with backing growing quickly for the Greens – driven by youthful and anti-Israel Jews – while more senior traditional men lean toward Reform UK as confidence in the leading parties “plummets”.

Backing of the Conservative and Labour parties among British Jews had fallen to 58% by July 2025 from nearly 84% in 2020, as per a study from a prominent research institute, which stated it was “the smallest share we’ve observed by a wide gap”.

Traditionally, Labour is favored by more “secular” Jews while the Conservatives is historically backed by more “observant” Jews.

Meanwhile, roughly 18% of Jewish individuals in Britain (18%) were backing the Green Party by June 2025 – which analysts called “surprising” given its policy on Israel, which it labeled an “segregationist regime” in a vote at its 2024 party conference.

Approval of the Green party increased 9% among the Jewish community between the 2024 general election and June 2025, outstripping the 1% growth in approval of the Green Party among the broader voting population over the equivalent interval, and coming before the guidance of a well-known figure who identifies as a “devout” Jew but “non-Zionist”.

The study said the growth in Greens support implied “for a sizable segment of Jews, domestic priorities and liberal ideals outweigh international affairs”.

At the same time, approval of the Reform Party rose among the Jewish community from 3% in August 2024 to 11% in the following year. But the rise fell behind the 14% increase the Reform Party received with the broader voter base.

“Jews remain less likely [than the broader public] to support Reform UK [11% vs 28%], but more prone to back the Greens [18% vs 7%],” the study said.

A prominent expert remarked: “The Reform Party is more prone to attract men, more senior, orthodox, and Zionist Jews; the Greens are more prone to draw youthful, unaffiliated and anti-Zionist …[but] it is essential to acknowledge that it is also a component of a larger, broader shift driving the national electorate as a whole.”

Still, the “surge in approval among the Jewish community for Reform UK – a organization whose language on border policy and national identity would normally be expected to alienate ethnic groups, including Jews” was labeled “remarkable” by the study.

“Large segments of the Jewish population may move toward parties offering resolve and direction, despite political history” when mainstream parties were viewed as “weak or hostile”, it added.

The study declared: “For the earliest occasion in contemporary British Jewish records, support for the Labour and Conservative parties together has declined to less than 60%.

“Given that this is mirrored in wider society too, it is not just a data outlier – it may suggest a fundamental change in Jewish electoral behavior.

“Several factors seem to be driving this splintering: the war in Gaza and its divisive impact on community views; increasing hostility towards Jews, resulting in a major violent incident at a religious center; and a wider erosion of faith in established parties.

“In combination, these factors are guiding Jews toward parties that provide direction – be it through populism or radical progressivism.

“If ongoing changes endure … British Jews are expected to become more politically polarised, leading to more strain among Jewish groups.”

The research body, which follows population shifts, interviewed 11,000 Jewish residents of Britain for the study, named The end of two-party politics? Emerging changes in the political preferences of UK Jewish voters.

It found that in the election year, Jewish electors were more prone than the general population to vote for the leading parties, with 44% supporting the Labour Party, compared with 34% of the electorate as a whole, and 32% supporting Conservative, against 24% of the wider electorate.

By mid-year, approval of the Labour Party had declined by 13% among the Jewish community, compared with a 9% drop with the wider electorate, while approval of the Tories among the Jewish community declined by 4%, equaling the broader population. “Low and stable” support for the Lib Dems has moved from 8% to 9% among UK Jewish voters.
